I have a background in statistics and was interested in learning more about modeling with Stochastic Differential Equations. I understand the basics of stochastic processes and measure theory, etc., as well as differential equations and numerical methods. I started to read Evan's short guide to SDEs which is nice. But I find myself getting a bit lost in a lot of the formalisms for defining martingales and then brownian motion, etc. I tend to find it hard to simply read equations instead of seeing someone explain the derivations--especially for a new topic.
I was hoping someone could recommend some online videos or online course on Stochastic Differential Equations. I found a lot of videos on Youtube and google, but was not sure which of them are good. Many of those videos are very incomplete, etc. Any help would be appreciated.
Thanks.
